At 67 years old, Les Iden, a retired public administrator, has been racing for four years. This Grand Prix came into his possession three years ago, and as he remembers, "I wanted a full-size classic Pontiac for comfortable cross-country travel to regional and national Pontiac events, and the '68 GP is the last of the great 'B-body' Grand Prixs. My wife and I have criss-crossed the U.S. in complete comfort in this car, and it's fast!" Not just a highway cruiser, this GP also took gold at POCI. Les is married with 4 adult sons and 11 grandkids, and his current Pontiacs include a '66 GTO post coupe that has been featured in HPP and a '72 Firebird T/A clone setup for the road course. | STRIP TUNING LOG | | Run/Tuning | Launch RPM | Shift Pt. | 60-ft | 1/8-mile | 1/4-mile | | 1. 35 psi in tires; 4 psi fuel pressure | Idle | 5,000 | 2.2 | 9.32/76.26 | 14.65/91.34 | | 2.
